JBJ TrueTemp Titanium Heater TG2-400 — Professional-Grade Digital Heating for 60–100 Gallon Aquariums
The JBJ TrueTemp Titanium Heater TG2-400 is a professional-grade 400-watt digital aquarium heater engineered for precise, reliable temperature control in freshwater and saltwater aquariums from 60 to 100 gallons. The JBJ TrueTemp Titanium Heater TG2-400 features a virtually indestructible corrosion-resistant titanium heating element that delivers consistent, efficient heat transfer across the larger water volume of a 60–100 gallon system — without the shattering risk of glass heaters or the corrosion vulnerability of stainless steel elements in saltwater environments. The precision digital touch pad controller delivers ±0.5°F accuracy with a large LED display showing current temperature at all times. The remote temperature probe — placeable up to 5 feet from the heating element — ensures accurate ambient tank readings across the full depth and width of a large aquarium. ETL approved for freshwater and saltwater use.

Why Titanium Beats Glass at 400 Watts
At 400 watts, a heater failure in a 60–100 gallon aquarium can be catastrophic. Glass heaters at this wattage carry significant shattering risk during water changes when cold water contacts a hot element. The JBJ TrueTemp Titanium Heater TG2-400 eliminates this risk entirely. Titanium cannot shatter under thermal shock, does not corrode in saltwater, and maintains structural integrity indefinitely. For high-value reef tanks and large saltwater systems, titanium is not optional — it is essential.
Remote Probe — Precision Across Large Water Volumes
In 60–100 gallon systems, temperature stratification across the water column is a real and measurable phenomenon. The JBJ TrueTemp Titanium Heater TG2-400’s remote probe placed up to 5 feet from the heating element measures true ambient tank temperature rather than the localized temperature near the heater — preventing false on/off cycles and maintaining the consistent temperature stability that fish, corals, and invertebrates require.
